Homework Statement



A particle of charge q and mass m is traveling in the lab with velocity v in the x direction when it encounters a constant E-field in the y direction. State the non zero components of the Faraday tensor in the rest frame of the lab.


The Attempt at a Solution



I said
E=E_{x}i + E_{y}j + E_{z}k
As the field is in the y direction
E=E_{y}j

Thus I believe the faraday tensot to have 2 non-zero components.
F^{02}=-E_{y} and F^{20}=+E_{y}

This does not seem right as the next part of the question asks for the equations of motion for the particle which I get out as a load of 0's.

Am I missing a magnetic component, and if so, how do I get it?

Regards

Don't replace Ey with F01 + F10, if that's what your doing.
 
just realized i got the indicies wrong. Now the original post is correct.
 
Thread 'Need help understanding this figure on energy levels'
This figure is from "Introduction to Quantum Mechanics" by Griffiths (3rd edition). It is available to download. It is from page 142. I am hoping the usual people on this site will give me a hand understanding what is going on in the figure. After the equation (4.50) it says "It is customary to introduce the principal quantum number, ##n##, which simply orders the allowed energies, starting with 1 for the ground state. (see the figure)" I still don't understand the figure :( Here is...
Thread 'Understanding how to "tack on" the time wiggle factor'
The last problem I posted on QM made it into advanced homework help, that is why I am putting it here. I am sorry for any hassle imposed on the moderators by myself. Part (a) is quite easy. We get $$\sigma_1 = 2\lambda, \mathbf{v}_1 = \begin{pmatrix} 0 \\ 0 \\ 1 \end{pmatrix} \sigma_2 = \lambda, \mathbf{v}_2 = \begin{pmatrix} 1/\sqrt{2} \\ 1/\sqrt{2} \\ 0 \end{pmatrix} \sigma_3 = -\lambda, \mathbf{v}_3 = \begin{pmatrix} 1/\sqrt{2} \\ -1/\sqrt{2} \\ 0 \end{pmatrix} $$ There are two ways...
